Some suggestions

It would basically be implementing something similar to what Steam offers, where users can chat directly with the friends they’ve added. Additionally, an interesting feature that could be integrated (and that would be up to each user) would be the option to add, next to the username or in an additional field (with the user’s choice, of course), their Discord username. This would allow users to also connect on Discord, making it easier to interact and communicate with those already added on Hydra, creating a more integrated and social environment for everyone.

A profile system could also be implemented, where users could add signatures to other people's profiles, allowing them to write things to their friends/acquaintances.

Also, in the catalog button, the option to choose which page to go to by typing the desired page number could be implemented. This would be useful because currently, for example, if I’m on page 100 and want to go to page 300, it’s not possible. This button would help a lot in this regard.

A friend search by profile ID or by friends, so we can more easily find our friends or the people we want to add.
